日本語
オランダの最終消費が世界にもたらす生物多様性損失を、生産層分解分析により初めてMSA指標で定量化した研究。2015年の損失は1600万MSA-loss·ha·yrに達し、59%が海外の上流サプライヤー由来だった。住宅と食料が最大の寄与源であり、消費カテゴリーごとに異なるサプライチェーン主体を政策対象とすべきと結論づける。
English
This study applies production layer decomposition to biodiversity footprints for the first time, quantifying Dutch consumption's global biodiversity loss in Mean Species Abundance terms. Of 16 million MSA-loss·ha·yr in 2015, 59% originated from upstream suppliers abroad, with housing and food the largest contributors. It argues that policies must target different supply chain actors depending on consumption category.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも生物多様性の開示要請（TNFD等）が高まる中、消費ベースのフットプリントをサプライチェーン上流まで分解する手法は、企業のScope 3・自然資本評価やSSBJのサステナビリティ開示を検討する上で参考になる。
In the global GX context
As global frameworks like TNFD and CSRD push nature-related disclosure, this paper offers a replicable method for attributing biodiversity impacts across supply chain layers, complementing TCFD-style climate risk analysis with nature metrics. It highlights the need for consumption-based accounting in international disclosure standards.
👥 読者別の含意
🔬研究者:生産層分解を生物多様性フットプリントに適用した先駆的手法と、国別消費ベースの損失配分データを提供する。
🏢実務担当者:自社サプライチェーン上流の生物多様性影響を把握し、カテゴリー別に優先対策を検討する際の枠組みとして活用できる。
🏛政策担当者:消費ベースの生物多様性損失を削減するには、国内・国際的なサプライチェーン別政策が必要であることを示唆する。
📄 Abstract（原文）
Unsustainable consumption patterns, through factors like land use, greenhouse gas (GHG) emissions, and pollution, are significant drivers of global biodiversity loss. In this paper, we demonstrate the usefulness of unravelling biodiversity footprints, including the direct and indirect biodiversity impacts of final consumers, in order to examine the location of impacts on biodiversity in the supply chain of consumption. We do so by performing a production layer decomposition, which is novel for biodiversity footprints. We illustrate this method for the Netherlands as an example of a high-income country and for biodiversity footprints that are expressed as losses in Mean Species Abundance (MSA). In 2015, Dutch consumption resulted in 16 million MSA-loss·ha·yr all over the world. Of these losses, 12% originated directly from consumers, 29% from production within the Netherlands for Dutch final demand, and 59% from upstream suppliers that were based abroad. Losses due to final consumers themselves, mainly households, include land use for housing, or GHG emissions from motor fuels. Overall, housing and food contributes most to the Dutch biodiversity footprint. Our decomposition analysis shows that housing also generates the largest loss in sectors directly producing for Dutch consumption, while goods and services have more losses further upstream in their supply chains. The relevance of our findings is that to reduce biodiversity impacts of consumption, actors in different parts of the supply chain have to be targeted depending on the consumption category. Our study emphasises the necessity for specific policies per product supply chain, both national and international in scope, to reduce global biodiversity loss, going beyond direct suppliers.
